Anyone who contributes to a thread on the Sidmouth Festival in the U.K. suffers the same fate - a whole host of bile from someone who calls him/herself 'Lizzie from Sidmouth'.
All sensible debate ends up in a slanging match that does nobody any good... and the Festival itself a great deal of harm.
Without wishing to stifle debate or introduce censorship there must surely be a way of dealing with trolls who only want to cause conflict and use mudcat to peddle their own bigoted and negative views.
